@SuperOniichan I actually enjoy SEED; its first half actually does a pretty interesting job of modernizing the original Mobile Suit Gundam storyline. I have few issues with it, really only wishing Kira was a little less melodramatic. By which, I mean that the emotional trauma that he's put through over the course of the series, while being perfectly appropriate to the plot and the characters, feels like it becomes a little trite the longer the series goes on because of how... Overacted? Yeah, overacted, soap-opera-y, is probably the best way to put it. They try to really hammer it home that Kira's traumatized by his experiences and being a Coordinator on the side of Naturals, but they just overdo it at times. Which, in all honesty, probably has to do with the fact that Kira was originally supposed to die during his duel with Athrun, but he was super popular, so they had to do rewrites.
As for Destiny, it tries to be the modern Zeta, so edgy angst is basically the name of the game, and it
might resonate with teenagers, but to everyone else, it just comes across as cringeworthy. Shinn's background, that of a war orphan who was traumatized by losing his family to a crossfire, and joins the military in hopes of preventing similar losses, sounds good on paper. In execution, however, he blames ORB for his losses, aka his home nation that was attacked for not picking a side, and the fact that he lashes out at practically
everyone, even personally killing the one person who was nice to him in his worst moments, makes him just so unlikable. Then you have Athrun basically go against his character development from SEED to rejoin ZAFT, have Mira Campbell become a fake Lacus, while the real Lacus becomes a bit of a Mary Sue; then you have Mu La Flaga's heroic sacrifice from SEED get completely overturned (only part of me is upset at this, because it means Murrue Ramius gets a happy ending), as well as Andrew Waltfeld's death getting reversed (without reversing his wife's).
It all honestly comes across as them saying "hey, remember everything you loved about SEED? Well, get ready for all of that to have meant absolutely nothing!"
